' Be it known that 1, JAN BRoNs,a subject of the Queen of the Netherlands, residing at Dejlfzijl, in the Kingdom of the. Netherlands, have invented a new and useful Hydrocarbon-Engine, of which theffollowihg is a' specification.

, In the application fora U. S. patent forhydrocarbon-engine filed by me and Nanno Timmer on July 1, 1904:, Serial No. 214,927 -tide also the German Patent Specification No. 167,149 and the British Patent Specification No. 149,165 of the year 1904) a four stroke cycle hydrocarbon-engine is described, in which air and liquid combustible are simultaneously admitted to the cylinder, butthe' mixture formed is utilized in two separate periods, partly by explosion and partly by combustion, under the direct influence of the-working piston.' -,In the said hydrocarbon-engine the air andthe liquid combustible are separately admitted to the cylinder through special valves, the former through the ordinary air inlet-valve and the latter through -another valve to the sprayer. Experience, 'hmvever,- has shown, that the separate admission of the air and the liquid combustible is not advantageous for the following reasons: As the perforations in the sprayer require to be small so as to render it possible to utilize the mixture in twoseparate periods and as the walls of the sprayer are necessarily heated during the preceding ""-uex'plosions and combustions of the mixture so that the liquid combustible in the sprayer f is rapidly gasified, it follows that the air --contained 'in the working cylinder during the combustible in the sprayer. 'l

the compression stroke of the piston is not ableto enter thesprayer in a sufiicient quantity and to mix .witht-hegas developed from. he conse-' quence is, that the mixture so formed is hardly explosible, so that the force of theexplosion taking place in, the working cylinder in the proximity of the end of the compression stroke does not sulficiently penetrate into the sprayer for rapidly expelling therefrom by shocks the combustible through the perforations to the working cylinder;

My invention relates to an improvement in such four stroke cycle hydrocarbon-engines,

whereby the said defect is avoided; and the improvement consists man 1n ect1'ng device in which both the air and theliquid combustible are admitted'to the sprayer-through means of a-nut g I will now proceed to describe my invention with reference to the accompanying drawings, in .which I v 1 Fi ure l is avertical cross section through afoul" stroke cycle hydrocarbon-engine on the line BB in Fig. 2, an upper partwith the injecting device being shown in elevateriah It is provided with .an injecting de 'VlOQ-SllQWfl at F igs. 3 anda.

JAN BRONS, OF DELFZIJL, NETHERLANDS,

of the body If is formed'a seat for 'a valve the spindle g of'which is guided ato and is rigidly connected 'with a collarg by A helical spring inserted between the collar 9 and the guide '0 serves for pressing the spindle g upward and thus-closing thevalve g A space his I provided'in the'body Z2 above the valve 9 and communicates with the annular space beneath the guide 0. This annular space in turn communicates through holes to in the guide 11 with the space between the latter and 7 the collar g above. The collar 9 is on its periphery provided with-several vertical cuts or recesses whereby the spaces above and be-- neath it are put in communication with one guide Z) and in the-body b at c and bears on the spindle g of the'valve 9. Above the guide '0 the body is provided with a cylindrical chamber 00., whichcommunioates on vthe one handwith an air-inlet 0 .above and on the other hand through holes w in the another. An'upper spindle 1* is guided in the guide 0 with the space below between the collar g and the guide 0 In both bodies b andb is provided a bent channel a, which terminates in the above mentioned space it.

Theupper horizontal branch of the body b is .formedas a cook," the' plug 6 of which has a bent channel that communicates with-the channelaand can register with a hole,.in

which a-supplytube c for liquid combustible is secured in any known manner. The stem of the plug 6 is preferably provided with a handle e on which an indicator 6 for a scale at is fastened. It will be understood," that by adjusting the handle e in accordance with the scale (Z the quantityof liquid combustible admitted from the supply tube 0 to the channel a can be varied. Of course the cock 6 maybe replaced by a valve or the like. The sprayer i is of the kind described in the said patent specification, it being provided along itslfperiphery with a: series of small perforations 2 at a certain small height above its-bottom. v

Both the" injecting device just described and thecasing. f of an outlet-valve f are inserted int-he coverjic of the motor and are there secured in any known and approved manner, for example by means of 'a holding down plate g anda bolt 9 The crankshaft 0 is arranged to drive in any known manner a cam-shaft n at such a ratei that the latter makes but one revolution on; every two revolutions of the crank-shaft '0 as usual. On the-camshaft n are fastened two suitable cams "n n and placed at an angle to each-"other as usual. Above the "cam-shafth an axle p is disposed-in the casing u, and two levers p carrying rollers p are mounted to rock onthe axle 72 Two yertical rods 8 guided in suitable holes'of the casing u'bear on thetwo levers p and are pivotally connected with two two-armed .the sprayer i will be hot. tion stroke of the piston Z the vaTve 9 will them is visible. The same is the case with the other parts 8 and t.

The hydrocarbon-engine operates as. follows: Suppose the engine is running, then Durin the sucbe opened from-the respective cam "n by means of the corresponding parts 79 ,358, Q1

' and 9 so that the downwardly movlng 131$- ton l will suck air into the cylinder 3 through the air-inlety, the chamber 11:, the holes/w in the guide 02 the space between the guide '0 and the collar 9 therecesses in the collar ,1 the space between the collar g and the guide 4;, the holes'w, in the guide 4)., the spaces betweenthe guide oand the valve g, the sprayer z'iand the perforations z of ,thelatter, and at the same time a small quantity of liquid" combustible will be drawn in. from the channel a through the space it into the'sprayer i, which it may fill about up to the perforations z. The

'areas of the channel a and of the cylindrical chamber :12 are so proportioned and the plug 6 is so adjusted by means of its hantible is drawn through the opened valve g, so-

that'inost of the air passes freely through the small perforations a into the cylinder 7'. Only a very small part of..the liquid combusthegas so formed mixes with the air sucked in, partly within the sprayer i'and partly in the cylinder j, so that the mixture filling .the cylinder is very weak and'therefore inexplosible. On the piston Z' .app ntiachin itsliquid-combustible; within the sprayer 2' will reach the perforations 2, so that the air passing through the same will carry off the gas developed and particles of 'hot liquid combustible about to be gasified. Shortly before the end of the downward stroke of the piston Z the valve 9 will be closed. On the piston Z reaching its lowest position it will be again moved upward by the live force of the two fly wheels 0 0 withthe aid of the crankshaft 0 and the connecting ind 'm; o compress the contents. the upper part or stratification of the air in the proximity of the sprayer i will be more strongly impregnated with gasified combustible than the lowerpart, so that an explosible mixture is formed only near the sprayer. Inthe proximity of the highest position of the piston 12 the compressed 'explosible mixture will attain so high a temperature as to be capable of igniting itself, when a weak explosion and an increase of the temperature and the pressure will follow. A ftcr the pas- It is evident, that tible will be gasified by the hot sprayer i and lowest position the slowly rising level 0 the sage of the crank-pin through the dead point "the exploded mixture will drive the piston Z downward during the third'stroke,

while the combustible in thesprayer z' isforced out partly in its gasified state (due to he heat of the sprayer z and. the product) and partly in its liquid state either through the shock due to the explosion, or through the sucking elfect of the pison'l, since the latter in going downward increases the volume of the contents, so that the pressure in the sprayer i varies, it either gradually or periodically exceeding that in the cylinder. The combustible thus injected into the cyliuder gradually mixes with the hot air still left unburned in the cylinder and sustains the combustion, so that not only the mixture is prevented from cooling, but also the driving power is constantly supplemented and the piston Z is moved downward more uniformly than in ordinary explosion-engines.

During its fourth stroke the piston Z 15 forced upward by the l1ve force of the two fiy-Wheels 0 0 and the outletalve f is opened to permit the burned gases to escape. Afterward all the'occurrences described Wlll repeat.

' By turning the fly-wheels r) with onc's hands or otherwise the "valve g is opened and so much liquid combustible is permitted to flow into the sprayer i, that a small quantity of it overfhws through the perforations and drops on the piston Z. The turning of the fly-wheels is continued, so that at the end oi the compression stroke of thepiston Z in the first cycle the small quantity of liquid combustible on the piston is gasified and may be ignited at once, or the gasified conibustible will beignited after a few cycles at the end at the compression stroke, so that the sprayer '2 will become hot and be capable of gasifying thecombustible, when the enme will be able to work. 2)

Trials with the indicator have proved, that r the hydrocarbon-engine provided with the new injecting devicewill yield from 10 to 15% more useful effect than one with the old injecting device disposed separately from the air-inlet valve. 1

The new injecting devicev may be aried in many respects without departing from the spirit of my invention.
